LPN Fundamentals of Nursing

Correct Answer: A

Rationale: Encouraging the use of an incentive spirometer is crucial in preventing respiratory complications postoperatively. The incentive spirometer helps the client perform deep breathing exercises, which can prevent atelectasis (lung collapse) and promote lung expansion. This, in turn, reduces the risk of respiratory complications such as pneumonia. Restricting fluid intake, placing the client in a supine position, and administering a cough suppressant are not appropriate actions for preventing respiratory complications in a postoperative client.

Correct Answer: C

Rationale: Crackles in the lungs are a classic sign of fluid volume overload. When there is an excess of fluid in the lungs, it can manifest as crackling sounds upon auscultation. This finding indicates the accumulation of fluid in the alveoli and interstitial spaces of the lungs, which is a common manifestation of fluid volume overload.

Correct Answer: C

Rationale: Increasing fiber intake is a beneficial dietary modification for clients with hypertension. Fiber helps in reducing blood pressure and improving cardiovascular health by promoting better digestion and regulating cholesterol levels. Therefore, advising a client with hypertension to increase fiber intake can be beneficial for their overall health. In contrast, increasing sodium intake can lead to higher blood pressure, reducing potassium intake is not recommended as potassium helps in regulating blood pressure, and reducing calcium intake is not typically necessary for hypertension management.

Correct Answer: B

Rationale: The client's self-report of pain is the most reliable indicator of pain. Pain is a subjective experience, and the client's self-report provides direct insight into their perception of pain intensity, quality, and impact on daily life. Vital signs, body language, and medical history can offer additional information but may not accurately reflect the client's actual pain experience. Therefore, relying on the client's self-report ensures a more accurate assessment of their pain and helps in tailoring appropriate interventions and treatment plans.

Correct Answer: A

Rationale: Flushing the NG tube with 30 mL of water every 4 hours is crucial to maintain its patency and prevent blockages. This routine ensures the tube stays clear and functional, enabling proper delivery of medications and nutrition to the client. Regular flushing also helps prevent residue buildup or clogs within the tube, reducing risks like aspiration or inaccurate medication dosing.
